i took everyone's advice and got a Kelty Teton 2 (there was another post). I got it for around 89. It packs at 4lbs and 10oz. Has plenty of head room so i can hang wet things in there at night and do various other things. I think i'll be pleased. It should be here tomorrow so i'm going to sleep in the yard.

also, if you are tall, check out campmor.com for the Kelty Mistral tent. I think it's rated at 15 or 20 degrees and it's longer than a normal bag and only cost 37 bucks!
